    Description copied from interface: NaNTransformer
    Pre-process the data for partitioning.
    This method will scan all the data and apply processing to NaN values.
    The method will return:
    
    An array to partition; this may be a copy.
    The bounds of the returned data as [start, end); this can be smaller than the input range if the transformer is configured to exclude NaN values. The start is inclusive and the end is exclusive.
    
    Implementations may assume the input [from, to) range is valid given the length of the data array.
    Specified by:
    
    apply in interface NaNTransformer
    
    Parameters:
    
    data - Data.
    
    from - Inclusive start of the range.
    
    to - Exclusive end of the range.
    
    bounds - Set to [start, end).
    
    Returns:
    
    pre-processed data (may be a copy)
